bridge pavement grooving, which type is best?

[InterstateGuy]

I know this has been a topic that has been discussed before but i am curious as to know which type of concrete grooving you prefer on bridges. in NY we now use Longitudinal, used to be latitudinal. My car kind of gets bumpy going northbound on the Longitudinal grooving on the Robert Moses Causeway as opposed to the latitudinal southound lanes which makes the cool tie fighter jet type of noise. Is latitudinal in your opinion better than longitudinal? Which keeps the car more stable (from your own experiences)?

Latitudinal groves 1/4 inch across with spacing 1/4 to 1/2 makes a sound with some tires that reaches the threshold of pain for those along the side of the road. I have no intention of having these removed since they are there for traction. The best way to drain water off the road is to have them at a diagonal on the slopes. This should also reduce the decibels. Herringbone design on gears are there to reduce the noise.

I've always seen "transverse" as opposed to "latitudinal" in reference to any feature that is orthogonal to the direction of travel on a roadway.
